NEET2014ChemistryHydrogenActual
Which is correct regarding acidity?
Options
- AH ₂ ~S < H ₂ Se
- BH ₂ ~S > H ₂ Se
- CH ₂ Se > H ₂ Te
- DNone of these.
Correct answer
A. H ₂ ~S < H ₂ Se
Step-by-step solution
Due to decrease in bond ( H -E , where E= O , S , Se , Te ) dissociation enthalpy down the group, acidic character increases. Hence, the order is : H ₂ O < H ₂ ~S < H ₂ Se < H ₂ Te
